Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); crossotus: From the Greek krossotos, fringed, referring to the branched filament of this species.
Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin bathypélagique; profondeur 0 - 330 m (Ref. 11333). Deep-water
Western Pacific: between 10°-20°N and 120°-140°E, the South China Sea, and off the Solomon Islands.
Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 12.8 cm SL mâle / non sexé; (Ref. 11333); 15.4 cm SL (female)
Rayons mous dorsaux (Total) : 25; Rayons mous anaux: 38; Vertèbres: 68. Two terminal bulbs separated by a short interspace, 0.3-1.5 times length of distal bulb. Barbel 52-63% SL in specimens larger than 8 cm. Terminal filament long (11-22% SL except in smallest specimen; with 2-4 long branches arising closely together a short distance (less than 0.5 to about 1.3 distal bulb lengths) from distal bulb. All branches with very small bulblets and without sub-branches. Stem axis well pigmented except in smallest specimen (6.6 cm); stem between bulbs and proximal part of filament usually lightly pigmented. Middorsal paired spots under skin between occiput and dorsal-fin origin usually 8, sometimes 7 (Ref. 11333).
Body shape (shape guide): elongated.
